Los Angeles (CNN) - Transgender students in California would be able to choose which school bathrooms and locker rooms to use and which sport teams to join based on their gender identity under a measure approved this week by the California Legislature.

The proposal now awaits the signature of Gov. Jerry Brown, whose office has declined to comment on whether he will sign it.

The proposal would be the first state law in the nation that specifically requires equal access to public school facilities and activities based on gender identity, though some states have general policies to the same effect, said Shannon Price Minter, legal director of the National Center for Lesbian Rights, one of several groups backing the legislation.

But enactment of the measure would "simply mean that California will be catching up with other states that already have enacted regulations based on a general prohibition of gender identity discrimination in schools," Minter told CNN.

(CNN) - I walked into the room hoping no one would discover my secret.

I feared my accent would betray my identity, so I kept silent. I glanced self-consciously at my cheap clothes, wishing I could afford better. I stared at the photogenic, self-assured students around me as if they were from another planet.

For me, they were from another world.

I was a 17-year-old African-American from an impoverished, inner-city community and had no idea what I was getting into. Next to me in a college freshman orientation class were students who came from private schools and grew up in homes with swimming pools and maids.

But here was the catch: I wasn't an affirmative action enrollee at an elite white university. I was a black student thrust onto the campus of a predominantly black university. My hang-up wasn't race; it was class. I was suffering from "class shock." I was on a path to self-destruction because I didn't know how to cross the bridge from poverty into this strange, new world.

I thought about that period in my life after learning last week that the U.S. Supreme Court had upheld the use of race in college admissions but had signaled that it may soon abandon that position. People are already preparing for what may come next: Colleges are going to create diversity by using class instead of race. Some call it economic affirmative action.

It is something liberals and conservatives seem to support. That's part of its appeal. Such an approach would create diversity on college campuses without resurrecting the endless wars over race-based affirmative action.

Richard Kahlenberg, dubbed the "intellectual father" of economic affirmative action, says the current approach to affirmative action in higher education does not help many poor black students.

In his paper, "A Better Affirmative Action," Kahlenberg cited research that found 86% of contemporary black students at selective colleges were either middle or upper class.

Class-based affirmative action is something all kinds of Americans - including conservative justices on the Supreme Court - could support, he says.

"Even the most right-wing justices, like Clarence Thomas, have said that they support the idea of race-neutral affirmative action for economically disadvantaged students," he says.

Maybe so. But my experience suggests that there is a hidden challenge to such an approach. Placing poor students in top-tier colleges is only half of the battle. There's another psychological battle that some of these students will fight within themselves, and, as I found out, there's no college prep course out there to help.
